Fill in the Blank

An operations supervisor at a chemical storage facility is reviewing safety compliance protocols. The safe operational temperature variance xx (in degrees Celsius) of a cooling tank is modeled by the compound inequality 34x−3≤3\frac{3}{4}x - 3 \le 3 or 25(x+10)≥0\frac{2}{5}(x + 10) \ge 0. After solving, these conditions simplify to x≤8x \le 8 or x≥−10x \ge -10. Recalling the mathematical definition of a compound inequality joined by the word 'or', the supervisor knows that the final combined solution set is the
